US Federal Tax Brackets 2024-2025: How They Actually Work

How Tax Brackets Actually Work

The biggest misconception: "If I earn more, I'll lose money because I'll be in a higher bracket." This is wrong. Only the income WITHIN each bracket is taxed at that rate — not your entire income.

2024 Federal Tax Brackets (Single Filers)

• $0 – $11,600: 10%
• $11,601 – $47,150: 12%
• $47,151 – $100,525: 22%
• $100,526 – $191,950: 24%
• $191,951 – $243,725: 32%
• $243,726 – $609,350: 35%
• Over $609,350: 37%

Example: $75,000 Salary

After the standard deduction ($14,600), your taxable income is $60,400:

• First $11,600 at 10% = $1,160
• $11,601–$47,150 at 12% = $4,266
• $47,151–$60,400 at 22% = $2,915
• Total federal tax: $8,341
• Effective rate: 11.1% (not 22%!)

Marginal vs Effective Rate

Marginal rate: The rate on your LAST dollar of income (22% in the example above).

Effective rate: Your actual overall percentage (total tax ÷ total income). Always lower than your marginal rate.

Ways to Lower Your Tax Bill
